Crime has always flourished in the high-rise buildings on the outskirts of the capital, in particular one block, known in slang as Novosiolki, and local residents are so used to the situation that no-one has been able to convince them that things could change. But it appears that life is about to improve with the appointment of a new district police officer, Sergey Gromov, a former senior investigator with the Homicide Department.

Sergey dislikes revisiting his past, but if his previous investigations have taught him anything, it is to quickly assess a situation and make a firm decision. Sergey, however, has not been assigned to solve cold cases, instead, his primary task will be to deter criminals and prevent future offences.
